Extract and Modify Field in a 32-bit Register

Code

#include <stdio.h>
#include <stdint.h>

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint8_t val = (reg >> 10) & 0x1F;
    if(val >= 31)
    {
        return reg;
    }
    val++;
    reg &= ~(0x1F << 10); // THis will clear the already set bits
    reg |= (val << 10);   // This will set the New Modified Incremented Vlaue

    return reg;
}

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    uint32_t updated = update_register(reg);
    printf("%u", updated);
    return 0;
}
